Wow thats some work to install that manifold. Like FR2oh, I would of pull the front end off. I removed my bumper yrs ago to remove the stock air cleaner & all the ducting to install a Steeda sri. Thats right about pull the p/s bolt on the bottom, you have to undue the hose to get the bolt out. I had to pull my front cover,= I forgot about the chain tensioner, when I installed my crane cams. It just added a couple more hrs. I been eyeing that manifold for yrs. Let us know how it runs. Subscibed.
